Hi,
1-It's complicated for me that how to choose inlet device ( no inlet device, half-open pipe, proprietary, cyclone and etc)? Based on what parameters? I know there is standards for that which if you choose half open pipe pv^2< 4200 and etc. But, these standards is used to find min nozzle diameter after deciding inlet device type right? Also, what does proprietary device mean ( special manufactured device or schoepentoeter) ? Some of references say that it's based on g/l ratio. Is that true?
2-If these standards ( pv^2<4200) is used for determining the type of inlet device, then how to calculate velocity without knowing ID of nozzle?
I have excel sheet. Which firstly calculates ID using pv^2 standard then calculates v using this ID then again calculates pv^2 for that velocity. But there is no information why it chose the proprietary inlet device
